The German Panzer or Tanker suit comes as a fully insulated option. It comes as a two-piece unit that zips in the front. OR get each piece individually. You may also take out the lining for warmer weather. They are great for snowmobiling, working outside in cold or warmer weather, painting or working on cars, whatever the case, if you need coveralls, these are great. There is a opening on the back that features and integrated rescue harness. It was designed for pulling the tankers out of a dangerous situation. Most of them have a German flag on the shoulder.
